Thanks for the advice, still not sure what I should do....
Gavilan: OK, if it's bad laser calibration, I assume I'd have to adjust the CD32 using Ian Stedman's guide on Aminet? Could you give me any advice about this? I have only 1 CD32, I really don't want to risk messing it up just because it won't read CD-R's....
Cammy: Thanks for the advice... but oddly, the Sony music CD-R, the only one that worked, is a 'darker' one (compared to Taiyo Yuden, TDK, Memorex, and other brands that look 'silver) ...
My burner + software can go as low as 2x , I'll try that next... I figured that since my SegaCD is cool with discs burned at 4x, the CD32 would be too....... grrr...
At any rate, thanks everyone....
